I've noticed a certain trend over the years where you get certain types of projects that get lots of hype and excitement and much progress seems to be made, but when you dig deep enough you find out that it's all just the fun, easy sort of progress.
The fun progress, which not at all coincidentallly tends to also be the easy progress, is the type that happens solely inside a computer.
What do I mean by that? I mean programs who only operate at the level of artificial computer abstractions.
The hard part is always dealing with "the real world": hardware that returns "impossible" results to your nicely abstract api functions, things that stop working in places they really shouldn't be able to, or even, and this is the really tricky bit, dealing with humans.
Databases are a good example of this kind of thing. It's easy to start off a database writing all the clever (and fun) bits like btrees and hash maps and chained hashes that spill to disk to optimize certain types of tables and so on, but I'd wager that at least half of the code in a "real" database like sqlite or postgresql is devoted to dealing with strange hardware errors or leaky api abstractions across multiple platforms or the various ways a human can send nonsensical input into the system and really screw things up.
I'd also bet that this type of code is a lot less fun to write and took much longer than the rest (which incidentally is why I always get annoyes when programming language demos show code with only a happy path, but that's another rant and this comment is already excessive).
Anyways, this AI thing is definitely a gold rush and it's important to keep in mind that there was in fact a lot of gold that got dug up but, as everyone constantly repeats, the more consistent way to benefit is sell the shovels and this is very definitely an ad for a shovel.
